Value Collection AP02.50 Aluminum Expansion Plug

Product Description

The VALUE COLLECTION AP02.50 is an aluminum expansion plug designed to seal pipe openings during pressure testing, maintenance, or system isolation. The plug expands from an unexpanded diameter of 2.440 inches to a maximum expanded diameter of 2.775 inches, providing a secure, leak-resistant fit inside standard pipe ends. Rated to 9 psi maximum working pressure, it is suitable for low-pressure applications in plumbing, HVAC, and light industrial pipework. The 1/2-inch stem diameter allows for straightforward installation and removal with common hand tools. Plumbers and pipefitters are the primary trades that install this type of fitting.

This expansion plug is used to temporarily or permanently cap pipe ends in residential and commercial plumbing and HVAC systems. Typical applications include pressure testing pipe runs, blanking off unused branch connections, and isolating sections of a system during repair or inspection. The aluminum construction makes it suitable for dry or moist environments where corrosion resistance and light weight are priorities. It is installed in any orientation and requires no special thread preparation on the pipe end being plugged.

Key Features

• Expands from 2.440 inches to 2.775 inches for a tight friction fit inside pipe ends
• Rated to 9 psi maximum working pressure
• Aluminum construction resists corrosion and reduces fitting weight
• 1/2-inch stem diameter for easy wrench or hand installation
• No pipe threading required on the receiving pipe end

Compatibility

Designed as an OEM-style replacement or direct-fit expansion plug for pipe ends accepting an unexpanded diameter of 2.440 inches and an expanded diameter of 2.775 inches in standard plumbing and HVAC piping applications.

Installation Notes

Installation is performed by plumbers or pipefitters following applicable IPC or local plumbing code requirements. Depressurize and isolate the pipe section before inserting or removing the plug. Use a properly sized wrench on the stem to tighten or loosen the expansion mechanism without over-torquing the aluminum body. Do not exceed the 9 psi rated working pressure when the plug is in service.
